a car with wheels of radius 0.380 m is driving 15.8 m/s. what is the angular velocity of the wheels?

Answer 1

The tangential velocity (v_T) and the angular velocity (ω) are related by the equation:

v_T = rω (where "r" is the radius) and solving this equation for ω gives:

ω = v_T/r

The tangential velocity is equal to the speed or the car so:

ω = (15.8)/(0.380) = 41.6 radians/sec

Answer 2

Angular velocity ω = v/r = 15.8m/s/0.38 m = 41.58 rad/s
